CLOCK.

Application filed December 21, 1922.

To C! 10. 10112. it may concern:

Be it known that I, EMMANUEL MATHEZ, citizen of the United States, residing at ihiglev'ood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Clocks, of which the following is a specification.

This invention relates to clocks and includes improvements with respect to stem winding and setting devices which makes I movable or detachable stem, which can be iii) detached when the clock is applied to the board and afterwards inserted or attached to serve its purposes.

The invention will be more clearly understood from the following description and the accompanying drawings in which Fig. 1 is a side elevation, partly in section, of the clock applied to front board. Fig. 2 is a section with the casing removed, on the 2-2 of Fig. 1. Fig. 3 is a rear plan of the movement. Fig. 4 is a detail in plan of the winding and setting gear. Fig. 5 a plan of the stem. Figs. 6 and 7 are i lare ed plan views showing the change of m and associated parts from winding to setting position. Fig. 8 is a section on the line 8-8 of Fig. 7. Fig. 9 is a plan of a lever for operating the shift from one po sition to the other, and Fig. 10 is a perspective view of the same.

The clock casing comprises a cup-shaped back section 6 and a similar front section 7 which fit together with lapped edges and which are fastened together with screws 8, and are mounted in a hole in the front board 9 which is shown with a flange 10 at the bottom, said flange having a hole thru which tits a tubular extension 11 on the side of the rear section 6 of the case. The winding stein works in or thru the tube 11 and has a knob 13 at its outer end. In order to enter the tube 11 in the hole in the flange 10, the stem and its knob must be removed, when the clock is applied to the front board, and the present invention permits this to be done, the stem being inserted after the clock is in place.

The movement used is preferably a watch moven'ient, and it is supported. in the casing by means of a bracket consisting of a ring Serial No. 608,173.

14 which has rearwardly projecting pillars which are fastened to the back plate of the casing as by screws 16. The movement, as a whole, fits between the pillars 15 as shown in Fig. 3, the front plate of the move ment being indicated at 17 and being attached to a ring 14 as by small screws 18, the back plate of the movement being indicated at 19.

A particular description of the whole movement is unnecessary, but the winding gear includes a wheel 20 on the spring arbor 21, and a shifting wheel 22 meshing with said wheel and with a pinion 23 driven by a pinion 24 supported by a bracket 25 and having a square hole adapted to receive the squared end 26 of the stem 12. The setting train includes a pinion 27, a wheel 28, and a pinion 29, which latter may be engaged by the wheel 22 when the stem is shifted in or out from winding to setting position or vice versa. Fig. 6 shows the winding train engaged and Fig. 7 shows the setting train engaged, the shift of the wheel 22 being shown in dotted lines in Fig. 2.

The means for effecting this shift include a lever 30 having an angular recess 31 in one end thru which extends the floating arbor 32 of the wheel 22, said arbor working laterally in a slot 33 in the front movement plate 17. The arbor carries a blank 34 which is pressed by a spring 35 which tends to throw the arbor and the wheel into engagement with the winding gear 20 as shown in Fig. 6. The lever 30 is pivoted between the movement plates by a pin 36 fastened thereto by an angular arm 37 projecting from the lever, and this pin 36 projects thru a bearing in the rear movement plate 19, which permits the lever 30 to rise and fall for a'purpose to be stated. The lever is provided with an angular yoke 38 the fingers 39 of which are adapted to engage a neck 40 behind a head 41 on the stem 12, when said lever is lowered, but when the lever is raised the lingers clear the head 41 so that the stem may be pushed in or pulled out to connect or disconnect the same.

When the lever is engaged with the stem, and the latter is shifted or pulled out slightly. as shown in Fig. 7. the arbor 32 and the wheel 22 carried thereby is shifted by movement of the lever from the winding position shown in Fig. 6 to the setting posilion shown in Fig. '1, against the tension of the spring 35, and when the stem is then pushed. in the wheel 22 is shifted or swung; over to winding position again, as shown in Figs. 2 and 6. Accordingly rotation of the stem 12 will thus operate either the winding train or the setting train.

It is obvious that as long as the fingers 39 engage the head ll on the winding stem the latter cannot be removed. This engagement is maintained or locked by means of a screw 50 which is tapped thru the back plate of the case, as shown in Fig. l, and in line with the rear end of the pivot pin 36 which, as stated, projects thru the back plate 19 oi the movement. Therefore when the screw 50 is screwed in, the stem being in place, the pin 36 will be pressed in or torwardly, causing the fingers 39 to enter behind the head 41, and this locks the lever to the stem so that the stem may be shifted in or out to change from winding to setting. To permit the stem to be detached and entirely removed. the screw 50 is backed off, and then by special effort or pull outwardly on the stem 12 the lever will jump up, as shown in dotted lines in Fig. 8, permitting the head to clear the fingers 39 and be pulled completely out thru the gear 24: and the tubular boss 11. A block 52 is placed on the pin 36 to limit the upward movement of the lever 30 and prevent the pin 36 from jumping out 0t its bearings, said hlorlr striking against the inner surface of the back plate 19 when the lever lifts sulficiently. The stem may be inserted the same way, and when the head passes under the yolte the screw is screwed in, carrying with. it the pivot pin 36 and the lever 30 and causing the fingers 39 to engage behind the head 41 and so lock the stem in its operative position. Therefore by themeans described it is possible to remove the stem, insert the clock in the front board, then replace the stem as shown'in Fin. 1 and then screw in the screw 50 to lock it in position.

The invention is not limited to the par ticular lieatures shown, but various changes may be made within the scope thereof as indicated in the following claims.

I claim:

1. The combination with a clock casing; and movement, of a detachable winding and releasahly lock said stem in engagement with the said train.

2. The combination set torth in claim l. means including a screw working; thru a wall of? the casing.

The coi'nhination set forth in claim 1 said means including a l ver having a fork engageable with the stem and a screw work ing thru the casing and against said lever to lock the same in or ragementwith. the stem.

4. The combination of a cloclr casing, a movement therein inclinlin winding: and setting trains and. a shittingwheel engageable with either train, a lever connected to said wheel to shitt the same, a removable winding and setting st m extending thru said casing and detachably e1 agging said lever, and means extending thrn the casing to lock said lever in engagement with the stem.

5. The combination set torth. in claim a, said means including a screw working thru a wall of the casing.

6. The combination set forth in claim 5, said lever being shittable laterally parallel to the axis of its pivot, and said screw engage'able with said pivot to prevent said shift.

7. The combination with a supporting board, of a clocl mounted. in a recess there in and having a winding stem projecting from the side thereof, said winding stem being detachable to permit the clock to be fitted in the recess.

8. The combination with a supporting board having; a flange with a hole therein of a clock mounted in a recess in the board, heside the flange. and removable winding stem insertible thru said hole in the flange to engagement with the winding: train of the clock.

S). The combination set forth in claim 8, the case of the clock having).- a tubular extension litting: in the hole in the flange. thru which. extension tl stem works.

In testimony w eot. T afiix my signature in presence of two witnesses.
